Do you mean your script will run on a system/network for which you have no prior knowledge? If that is the case, maybe you should consider tools other than nmcli. While it can be used, it may not be easy to tease out information in a way that is simply to correlate. You can do something like nmcli -f IP4.ROUTE d show and get all the ROUTE fields for all the devices but determining which belongs to which is not simple. You may want to consider the ip command. [egreshko@meimei ~]$ ip -br -4 add show lo UNKNOWN 127.0.0.1/8 enp2s0 UP 192.168.1.18/24 wlp4s0 UP 192.168.2.127/24 virbr0 UP 192.168.122.1/24 [egreshko@meimei ~]$ ip -br -4 route show default via 192.168.1.1 dev enp2s0 proto static metric 100 default via 192.168.2.5 dev wlp4s0 proto dhcp metric 600 192.168.1.0/24 dev enp2s0 proto kernel scope link src 192.168.1.18 metric 100 192.168.2.0/24 dev wlp4s0 proto kernel scope link src 192.168.2.127 metric 600 192.168.56.0/24 via 192.168.2.116 dev wlp4s0 proto static metric 600 192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 Tells you everything you need to know about networking on the host meimei. (Note: I used -4 in the example since I'm also running IPV6 and didn't wish add complication) You know that the default route will be via enp2s0 to 192.168.1.1 as long as enp2s0 is up. So, you'd naturally ping 192.168.1.1. You know that if enp2s0 is down then the default route will be via wlp4v0 to 192.168.2.5. So, if enp2s0 is down you'd naturally ping 192.168.2.5. -- The key to getting good answers is to ask good questions. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
